   The Egyptian SAKR Factory for Developed Industries has developed and placed in production the RL-4 122 mm (4-round) rocket launcher, which can launch locally produced SAKR-10 122 mm unguided surface-to-surface rockets. Production of these systems is undertaken by the SAKR Factory for developed industries on an as required basis.

   There are two versions of the 122 mm (4-round) rocket launcher: one mounted on the rear of a M720 44 cross-country truck chassis, however other types of launcher chassis could also be used. The other on a rapidly erected stand. Both of these have an optical aiming device for direct and indirect target engagement and a remote firing device. In the case of the former version, the manually mounted 122 mm (4-round) launcher is mounted on the rear deck. To provide a more stable firing platform four stabilizers are lowered to the ground: two are positioned at the front of the vehicle and two at the rear.

   When massed these rocket systems provide excellent firepower for light infantry units. Otherwise such units may be unable to get support from multiple launch rocket systems.

   The 122 mm (4-round) stand-mounted version has four adjustable legs, which can be adjusted to level the system prior to the rocket is being launched. While the 4-round launcher has a total traverse of 120 left and right it has a fine adjustment of 7 left and right.

   A SAKR-10 rocket is used for firing. It is a shorter and lighter version of the Grad rocket. However these rockets have reduced range and payload. Number in the designation indicated the maximum range. The rocket weights 46 kg opposed to 67 kg of the Grad rocket. Its minimum range is 3 km and maximum range is 10.8 km. These rockets feature S-form folding fins.

   Variants of the 4-round launch vehicle were seen in Lybia in 2011 and in Yemen in 2014. Various home-made launch vehicles were built on its basis in Lybia and Syria.
